thread-pool: avoid passing the pool parameter every time

Browse source 
thread_pool_submit_aio() is always called on a pool taken from
qemu_get_current_aio_context(), and that is the only intended
use: each pool runs only in the same thread that is submitting
work to it, it can't run anywhere else.

Therefore simplify the thread_pool_submit* API and remove the
ThreadPool function parameter.
